Embodiment 1
[0019] Gel particle 1# is produced by Daqing New Wantong Chemical Co., Ltd., and the particle size is 100-200 mesh; Magnetic stirrer (Changzhou Guohua Electric Co., Ltd.); Rheometer (MCR301 rheometer of AntonPaar, Austria), measuring The system is PP43 / GL-SN11457. Gel particle 1# is anionic gel particle, and the concentration of cross-linking agent is 0.21%.
[0020] The method for measuring the viscoelasticity of gel particles includes the following steps. The first step is to prepare a dispersion system of gel particles to make them fully swell. In a beaker with a volume of 250mL, add 100mL of simulated formation water, put a magnetic rotor, put the beaker on the workbench of the magnetic stirrer, turn on the switch of the magnetic stirrer to make the magnetic rotor start to rotate, adjust the magnetic stirrer Turn the knob into the beaker to form a swirl of simulated formation water. Weigh gel particles 1# with a mass of 1 g, slowly add the gel particles to the vortex wal...
